Answer: x= -2 and y=7
Step-by-step explanation:
4×20x+11y=37
20×4x+3y=13
Using elimination method
80x+44y=148
80x+60y=260
-16y/-16=-112/-16
Y=7
Substitute for Y in equation (1)
20x+ 11(7)=37
20x+77=37
20x=37-77
20x/20= -40/20
X= -2
therefore, x=-2 and y=7
Originally the ratio is 5:3, but we can make this ration 5x:3x because its equal. By doing so, we know that 5x+3x=32.
Now just solve the equation:
5x+3x=32
8x=32
x=4.
Now insert x into ratio.
Since she needs 3x of guava juice, she needs 3*4 fl oz of guava juice. She need 12 fl oz of guava juice.

We know that
the volume of a sphere=(4/3)*pi*r³
<span>The gumball has a sphere shape
</span>
find the volume of one gumball
volume=(4/3)*pi*r³
radius r=6mm
volume=(4/3)*pi*6³-----> 288*pi mm³
volume of 4 gumball=4*288*pi-----> 1152*pi mm³-----> 3617.28 mm³
the answer is
1152*pi mm³ (3617.28 mm³)

Answer:
To calculate what you need, multiply the walkway's width and length to find the square footage.
Step-by-step explanation:
To calculate what you need, multiply the walkway's width and length to find the square footage; for example a 4-foot-wide, 50-foot-long walkway covers 200 square feet. Next, factor in the thickness: 4 inches converts to 0.33 feet; multiply this by the square footage to find the cubic feet: 200 x 0.33 = 66 cubic feet.
